Triggering

Triggering Source

CH1, CH2, LINE, EXT(CH1and CH2 can be selected only when the vertical mode is DUAL or ADD). In ALT mode, if the TRIG.ALT switch is pushed in, it can be used for alternate triggering of two different sources.

AUTO: Sweeps run in the free mode when no triggering input signal is applied. (Applicable for repetitive signals of frequency 25Hz or over).NORM: When no triggering signal is applied, the trace is in the ready state and not displayed.TV-V: This setting is used when observing the entire vertical picture of television signal.TV-H: This setting id used when observing the entire horizontal picture of television signal.
